MCI was the first company to create agreements with the power companies in the USA to allow them to run fiber inside the center of the static wires that run along the tops of the transmission towers.
Hi Boys, Anyone of you actually used coax in this configuration? I have. Fed a 40m loop, tri-band Quad, mono-band beam and 160m dipole. The loops were fed with the shields tied together at the antenn
Hi Folks, Last year I installed a "Jamac" antenna in NVIS configuration for 40m. Just threw up two 140 dipoles, spaced 70ft apart and feed wtih 600ohm line. The elements are 15ft above earth (sandy l
Interesting Chuck...I've used Radio Works Line Isolators for a long time...never had any problems. Always place them between the exciter and amplifier...never had a reason to use them on the amp outp
Hi Folks, It's time to replace the tilt-up cable on the CT-100. There is a bolt that hold the cable to the side of the drum. Got the bolt loose but it's longer then there is room for it to exit the t

Hi Folks, Looking for the sacrificial bearing that goes with the subject thrust bearing. Please email direct with your price including shipping to Northern VA. 73s, dave wa3gin
Chuck, Not because I'm a VA amateur but I've used several of the Radio Works Isolators and in every case they have resolved my RFI problems which were due to RF floating on the shield of the coax. Ne
IF someone is buying a 89ft crank-up for the first time and don't have the foggiest idea how to install it...they prolly should stick with a ground mounted vertical or get some help from an experienc
Hi Folks, This weekend I took two old Butternut HF6V vertical antenna and mounted them end to end to create a rotating dipole. I had been using them as a phased array at a past QTH and they were just
Interesting...perhaps someone can tell me what is the gain of my NVIS system.: Four full wave dipoles (cut to 7mhz) at 15ft above four full wave dipoles (5% longer) laying on the ground. The driven e
